Title: Process and device for a two-step anaerobic treatment of liquid substrates
IPC: C02F3/28
Filed: 1989-03-10
Granted: 1992-09-02
Abstract: A process for the two-stage anaerobic treatment of liquid substrates with a high organic content in a reactor (1) with two inter-connected chambers (3,4), in the first of which the hydrolysis and acid fermentation (fermentation chamber) takes place and in the second of which the methane digestion (digestion chamber) takes place, the substrate being introduced into the lower region of the digestion chamber (5) and the sludge arising from the decomposed organic materials being discharged separately from the waste water element of the treated substrate (6, 12) and the fermentation gas and the biogas which have been formed being drawn off above the liquid level (8, 13). In order to further develop a process of the generic type in such a way that the whole process of substrate treatment is accelerated and, furthermore, to create equipment for the carrying out of this process which is constructed as simply as possible and, with respect to the optimum capacities of the fermentation and digestion chambers, can be easily adapted to existing circumstances, that is to say, the degree to which the substrate to be treated is loaded with organic matter, it is proposed that the substrate is fed to the two chambers in accordance with the discharge principle at about one third of the height of the relevant liquid level or lower and that the substrate is withdrawn from the fermentation chamber from above (14). <IMAGE>

Abstract: An assembly serves for operation of a damper door, in particular an air hole damper door or dome, which can be pivoted about a fixed first rotation axis (2) from a closed position into an alarm position and back again, with at least one linear drive element. At its end a first traverse part (1) of the damper door is fitted pivotably at a point on the damper door remote from the rotation axis (2), whilst its second end is fitted pivotably about a first pivot axis (11) on a supporting lever (12), which in turn can pivot about a fixed second pivot axis (13) close to the rotation axis of the damper door. In order to achieve a large opening angle of the damper door with only the single linear drive element, a supplementary deflection lever (15) is fitted with a first end pivotably on the first pivot axis (11) of the door. The second end of the deflection lever engages pivotably on the traverse part (1) of the damper door at a distance from its rotation axis (2) and from the fixing point (7a) of the first end of the drive element. <IMAGE>

Abstract: The invention improves the O2/O3 distribution in the ozone treatment of blood in a bottle provided for this purpose and prevents the development of relatively large gas bubbles, improves the effective cross-section and permits a reduction in the O2 and O3 portion in the supplied O2/O3 gas mixture. In the case of a bottle for ozonisation of blood for autohaemotherapy, of blood plasma or plasma fractions, into which the O2/O3 gas mixture produced by the generator is passed through a supply line mounted in the bottle stopper (3a) and is led down almost to the base (11) of the bottle, it is proposed to arrange a gas distributor extending over the whole base (11) of the bottle and generating small bubbles. For this purpose, for example a bundle of hollow fibres (9) made of physiologically inert plastic and with an internal diameter of approximately 0.4 to 0.6 mm can be provided for the gas supply, their outlet plane extending over the whole base (11) of the bottle. <IMAGE>

Abstract: Hexacarboxylic acid hexaamides are described which form lipophilic complexes with magnesium ions. These hexacarboxylic acid hexaamides can have an open-chain, or a monocyclic, bicyclic, tricyclic or polycyclic, total structure. The hexacarboxylic acid hexaamides are used as a magnesium-selective component in appropriate ion-selective parts of measuring arrangements for determining the magnesium concentration or activity respectively in liquid samples. Owing to the high selectivity for magnesium ions compared with sodium ions and the adequate selectivity for magnesium ions compared with calcium ions, the determination of the magnesium concentration in biological materials, for example body fluids such as urea, blood serum or whole blood, is possible using these membranes. In addition, determinations of this type can also be carried out in sample solutions which have a neutral or slightly acidic pH.

Abstract: A method for electronically detecting when a solenoid has closed, or nearly closed, indirectly senses changes in the inductance of the solenoid's coil as the solenoid closes. When the inductance has changed by a selected amount, the solenoid is assumed to have closed, or nearly closed, and current through the coil is promptly reduced. Preferably, changes in the inductance of the coil are sensed by establishing a plurality of current peaks in the coil, and sensing the current's decay time between peaks. When the decay time of a measured current peak exceeds the decay time of a previously measured current peak by a selected amount, it is assumed that the solenoid has closed, or nearly closed.

Abstract: A vacuum insulation panel having flexible gas impermeable walls (30,32) formed in multiple substantially adjacent compartments (35,39). A thermal break may advantageously be provided around the perimeter to prevent conduction of heat from a warmer side of the panel to a colder side, which thermal break can be easily constructed by utilizing webs of gas impermeable material with the foil carried thereon such that the foil has a width somewhat less than the width of the film and with two separate pieces of the film rotated at 90 DEG  to one another to provide a continuous area void of the foil. Multiple compartments (35,39) are utilized to enhance the long term thermal characteristics of the panel by "protecting" the vacuum characteristics of at least one of the compartments (35,39) by surrounding it with additional evacuated compartments. This results in a very minimal gas pressure gradient across the internal walls (31) forming the internal compartment to minimize gas and vapor permeation into it thus greatly enhancing the lifetime of the panel. Further, this permits strategic placing of gettering materials (34) such that gettering materials absorbing certain gases can be placed in the outer compartments and other gettering materials absorbing different gases can be placed in the internal compartments to enhance the lifetime of the panel. <IMAGE>

Abstract: The eddy current rail track brake has an adjustment bearing for holding the eddy current brake magnet 1 in its operative position, which bearing comprises a first adjustment part 33 on the eddy current brake magnet and a second adjustment part 34 on a non-sprung vehicle part. The first, upper adjustment part 33 is connected to the eddy current brake magnet 1 in a vertically and horizontally adjustable fashion, whilst the second lower adjustment part 34 is guided in a vertically displaceable manner on the non-sprung vehicle part 25 and can be lowered counter to the pretensioning of a pretensioned spring 30. The excitation of the eddy current brake magnet can be reduced as the travel speed decreases, in such a way that the attraction force does not exceed a specific maximum value. The pretensioning of the spring 30 is dimensioned to receive this attaction force without further compression of the spring 30. If the reduction of the excitation of the eddy current brake magnet 1 fails, the extremely high attraction force which occurs when the vehicle is travelling slowly or is stationary compresses the spring 30 and the eddy current brake magnet moves to the emergency position resting on the rail. As a result, overloading of the carrier elements of the eddy current brake magnet 1 is prevented. <IMAGE>
